Sure but there's a tradeoff with ground transport. A drone can make the trip with much shorter traveled distance and potentially higher speed, resulting in higher utilization per vehicle. It also doesn't interfere with road traffic, which could have externalities in longer idle time for other vehicles at intersections and whatnot.
